The air governor, located in the engine
compartment, regulates the air compressor to
cut-in and cut-out, keeping the air system in the
specified operating range of 105 to 120 psi.
Cut-in pressure of approximately 105 psi is
factory preset from the governor manufacturer
and is not adjustable. Cut-out pressure is calibrated
to 120 psi. When cut-out pressure is reached, the
governor will deactivate the compresssor.
The air tank should be manually drained once a month, or more, depending on
operating conditions where humidity is high. The air tank is equipped with a drain
valve for both the wet and dry side. Open the drain valves until all air is purged
from the tank, allowing five extra minutes for moisture to be expelled. Remember
to close the tank drain valves. The air tank has a pressure relief valve which is set
to release at approximately 130 psi.
Push-in fittings are used to connect air hoses between pneumatic
operated items, such as brake and accessory air systems located
throughout the motorhome. They are designed for quick and easy
maintenance and repair. Many sizes and types of fittings are available for
different applications. Threaded fittings adapt the push-in fittings to
connect pneumatically operated items. Main parts include the release
ring, locking ring, solid brass body and special rubber compound o-ring.
Damaged hoses can be repaired by using splices.
To Disconnect Hose:
• Push hose into fitting.
• Push release ring down against
locking ring portion of the
fitting body.
• While holding the release ring
down, pull hose away from
fitting.
